Teacher takes 3rd grade class to the horse races, and one boy decides he needs to go pee.
Teacher: “Anyone else need to go?”
To which a chorus of little boys answers: “Yes!”
So the teacher takes them to the Men’s Room and begins lifting them one by one so they can reach the urinal.
She picks one up, helps him unzip, and blushingly remarks:
“Oh my… you must be from the 5th or 6th grade!”
“No ma’am… I’m the jockey on horse # 3 in the next race.”
